When they were discovering Fossil Pokémon that were coming back to life, at the end of the riot they found a mysterious Pokémon egg. When the egg was hatching, Misty rudely bumped Ash out of the way, so Togepi saw Misty first. Because Misty was the first thing Togepi saw, Misty was now Togepi's "mother". Ash got annoyed, and there was a tournament for the egg. Ash won, but because Misty was Togepi's "mother", Togepi prefered Misty in the end (meaning that the tournament was totally useless).
